![]() Set to a phenomenal soundtrack from Jespyr Kyd, the game requires teamwork and some level of tactics as you switch between melee, ranged weapons and abilities to survive a grimdark onslaught.ĭriving the visuals is Fatshark's own branch of the Autodesk Stringray engine, as far as I can tell, and it uses a cornucopia of modern rendering techniques to create one of the most authentic-looking renditions of Warhammer 40K that I have seen to date. The gameplay is a mix of Chivalry, Left 4 Dead and Diablo - and of course, builds on Fatshark's previous work on the Warhammer Vermintide series. Let's start with the basics - the idea here is that you choose a character from one of four classes from the Warhammer 40K universe, embark on missions with up to three other players, complete objectives in dark dystopian envrionments and bring home gear and ability upgrades for your character. So what makes this first-person co-op title so visually commanding, how well does it run and what are the best optimised settings for mid-range and high-end hardware? It's particularly impressive given that developer Fatshark isn't using a mainstream engine like Unreal or Unity. There's a new `uvOffset` output that ones must add to the regular uv coordinates before a texture lookup if parallax must be taken into account (it is (0,0) if parallax is not used).It's not often that we see a PC-focused game that really pushes the platform hard, but that's exactly what Warhammer 40K: Darktide does - and its visual quality is astonishing. Parallax occlusion is enabled through a switch on the `PerturbNormal` block: If `normalMapColor` is not coming from a `Texture` block then parallax occlusion is disabled. That way, I can retrieve the sampler name used by that block and reuse it for sampling the texture myself (in the `parallaxOcclusion` shader function). ![]() Not looking for free lunches, Babylon.js is a huge free lunch alreadyįor parallax (not occlusion) mapping, you need to bind something to the `parallaxHeight` input (generally the alpha component of the normal map).įor parallax occlusion mapping, what I did to overcome the problem of sampling multiple times the texture is that it assumes that the `normalMapColor` input is coming from a `Texture` block. We need this functionality and we are intending to provide a PR, but need to understand both the problem and reservations about implementation possibilities fully, to make it easier. I’m sorry for all the questions, but I’m trying to understand the problem while lacking much of the ground-work, which I’m picking up not nearly fast enough. There is a lot of uniform preparation and other stuff, but at its core, the functionality is in the shader, right? Why can’t it be re-used in NodeMaterial? You mention reading multiple times from the normal map, isn’t this part implemented in the shader? If not, why can’t it be replicated in NodeMaterial? And last but not least, why would implementing a PerturbNormalWithParallax node as a stop-gap solution be overkill if it would provide a hacky but working solution to an otherwise unsolvable problem? In StandardMaterial and PBRMaterial parallax occlusion is activated by two defines: PARALLAX and PARALLAXOCCLUSION. PerturbNormal block activates BUMP define to do its work What I know isĪ) required functionality is in the standard shader and works with StandardMaterial and PBRMaterialī) NodeMaterial builds upon existing shaders, e.g. I feel like I’m still not understanding the issue preventing this.
